1.项目结构

2.实体类

package com.example.springrest1.entity;

import org.hibernate.annotations.GenericGenerators;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class User {
    @Id
    @GeneratedValue(strategy= GenerationType.IDENTITY)
    private long id;
    private String name;
    private String password;
    private int age;
    private boolean sex;

    public long getId() {

        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public boolean isSex() {
        return sex;
    }

    public void setSex(boolean sex) {
        this.sex = sex;
    }
}

3.仓储

package com.example.springrest1.repository;

import com.example.springrest1.entity.User;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;

@RepositoryRestResource(path = "user")
public interface UserRepository extends JpaRepository<User,Long> {
}

4.application.properties

server.port=80
#配置数据源
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
#mysql的驱动程序类
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

#连接池配置
spring.datasource.url=jdbc:mysql://localhost:3306/datatest?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.dbcp2.min-idle=5
spring.datasource.dbcp2.initial-size=5
spring.datasource.dbcp2.max-idle=5
spring.datasource.dbcp2.max-wait-millis=200

#配置自动建表：updata:没有表新建，有表更新操作,控制台显示建表语句
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true

#不加这句则默认为myisam引擎
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL55Dialect
